To convince me that ID is scientific the ID movement would have to act like a genuine scientific movement. Which would mean most of it going away. They don't need the lawyers or the PR and many of the Discovery Institute Fellows (some of whom are real embarrassments) could go.
But I don't think that the ID movement really wants to do that. As I've said before they want to give the appearance of being scientific when it's convenient just as they want to give the impression of being a religious movement when it is convenient.
The impression I get from the Wedge document is that they assumed that the science would simply fall into place. When it didn't, they decided it wasn't so important after all/
